A 74-year-old woman with Takayasu's arteritis previously underwent aortic valve replacement at 59 years old. She was initially diagnosed with aortic valve stenosis and valve detachment. Moreover, preoperative computed tomography revealed ∼40 mm distance between the coronary artery ostium and the prosthetic valve (PV) and an aneurysm at the sinus of Valsalva. A Bentall procedure was subsequently performed. Intraoperative findings revealed no detachment of the PV. Following PV removal, the subvalvular tissue was noted to protrude into the left ventricular outflow tract. Subsequently, it was revealed that the tissue could have interfered with the PV; however, the PV appeared to have been detached considering the imaging findings.
一位 74 岁的女性患有 Takayasu 动脉炎，曾于 59 岁时接受过主动脉瓣置换术。她最初被诊断为主动脉瓣狭窄和瓣叶脱垂。此外，术前计算机断层扫描显示冠状动脉开口与人工瓣膜（PV）之间有约 40mm 的距离，以及瓦氏窦处的动脉瘤。随后进行了 Bentall 手术。术中发现 PV 无脱垂。在移除 PV 后，发现瓣下组织突入左心室流出道。随后发现，该组织可能干扰了 PV，但考虑到影像学检查结果，PV 似乎已经脱垂。
